ABSTRACT

A new nephropid lobster, Hoploparia kamimurai new species is described from the Lower Cretaceous Ishido Formation (Barremian), Gunma Prefecture, central Japan. Two species of glypheid lobsters, Glyphea yoshiakii new species and Glyphea sp. were obtained from the Lower Cretaceous Arida Formation (Barremian), Wakayama Prefecture, southwest Japan and the uppermost Jurassic to lowermost Cretaceous Mitarai Formation (Tithonian–Berriasian), Gifu Prefecture, central Japan, respectively. These species are the fi rst records of the fossil Glypheidae from Japan.

Key words: Crustacea, Decapoda, Glyphea, Hoploparia, Lower Cretaceous, Japan.

RESUMEN

Se describe una nueva langosta nefrópida, Hoploparia kamimurai especie nueva del Cretácico Inferior de la Formación Ishido (Barremiano), Perfectura de Gunma, Japón Central. Dos especies de langostas glyféidas, Glyphea yoshiakii especie nueva y Glyphea sp. fueron recolectadas en depósitos del Cretácico Inferior de la Formación Arida (Barremiano), Perfectura de Wakayama, Suroeste de Japón, y en depósitos del Jurásico más alto al Cretácico más inferior de la Formación Mitarai (Tithoniano– Berriasiano), Perfectura de Gifu, Japón Central, respectivamente. Estas especies constituyen los primeros registros fósiles de la Familia Glypheidae de Japón.

Recently, a nearly Ajishima Island, Miyagi Prefecture, northeast Japan (Koseki entire specimen of cephalothorax and abdomen attaching et al., 1991).
